In air eleventh-hour attempt to escape penalties proposed by the Dartmouth Undergraduate Council, the college's Theta. Chi chapter yesterday voted unanimously to ignore the Caucasian restriction demanded by the fraternity's national board.

The vote came just after the Council had recommended to the college trustees that the fraternity be suspended from all inter-fraternity competition for at least a semester for falling to comply with the regulations established in the latter part of 1951 by the Council's Committee on Review of Fraternity Discrimination.

It is doubtful that the last minute vote will alter the Council's decision, but the fraternity may be reinstated next winter if it complies with the discrimination ruling.
